ATTACHMENT FOR TALKING-MACHINES.

To all whom it may concern:

Be it known that I, VV'uJJan S. MONA- NARA, resident of the United States, residing at San Francisco. in the county of San cial reference to a. mechanism adapted to be applied to such machines for the purpose of stopping the machine after the reproducing needle has covered a definite part of the record.

One object of the invention is to provide a mechanism whereby a machine of the class described may be stopped when the record is finished,

Another object of the invertion is to pro vide a device of this character which is adapted to be attached to any existing machine without change in the structure thereof.

"With the above and other objects in view the invention consists in general of an attachment for sound reproducing machines of the disk type arranged to stopthe motion of the diskat a predetermined point.

The invention further consists in certain novel details of construction and combinations oil parts hereinafter fully described, illustrated in the accompanying drawings, and s 'iecifically set forth in the claims.

in the accoln 'ianying drawings, like characters of reference indicate like parts in the several views, and Figure 1 is a top plan view of a portion oi a disk sound reproducing machine equipped with this invention, Fig. 2 is a partial side elevation oil such a machine. Fig. 25 shows the collar or clip adapted for application to the sound box of a talking machine. Fig. -it shows a view of a modilied form ot brake end. Fig. 5 is a second modification oi. the brake end such as used for machines employing disks or rocords larger than the revolving plate. Fig. 6 is a modil'icd -torn: ot the brake arm or slamlard. Fig. 7 is another modification therco'l. Fig. 8 is a modification showing a lug cast on the sound box of a talking 1nachine for the attachment of the step.

Specification of Letters Patent. v

Application filed October 6, 1909.

Patented Apr. 12. 1910.

Serial No. 521,219.

The numeral 10 indicates the box or casing of the machine and this machine is equipped. with the usual revolving plate 11.

At 12-is indicated the sound box and this sound box is of the ordinary shape and size.

The attachment forming .the subject of this patent comprises a collar or clip 13 arranged to fit over the sound box and secured thereto by means ot a suitable set screw 14. Through this collar or clip extends an opening 15 which is intersected by threaded openings 16 wherein is held a binding screw or set screw 17. Tl'nough the opening 15 em tends a brake standard 18 which has a downwardly bent outer end as indicated at 19. Tn the form ordinarily adopted this brake standard is provided at 20 with a suitable facing of rubber, leather or the like to constitute the brake. This "term may be modified by constructing the dowl'iwardly bent end with an opening therethrongh as indicated at '21, and when so modified, through this (melting extends a rod 22- having on its inner end the brake member as indicated at 23 and on its outer end a suitable grip This rod is held in position hv means of a set screw it secured in a threaded opening which intersects the opening )1.

In the mmlilication shown in Fig. 5 the opening 21 is replaced by a threaded opcning 2t; wherein is held a threaded brake screw 27 having a knurled head 28 and can rying a brake member-99.

ln thc nunlilication ol the standard shown in Fig. l) this standard is threaded as indicated al 30 while inthc modification shown in l ig. T the slundard has suitable scale. marks 31 thereon. in the case oi the form shown in Fig. ll'the opening 1:) threaded to permit the screwing ot' the standard in said opening so that the distance oi? the dowl'nvardly bent end l9 may be adjus'ed by said screw while in the other terms disclosed this distance is regulated by sliding the standard through the opening and adjusting the set screw 17 to hold it in position.

in the operation of any of these devices the standard 18 is set so that the needle rests in the last grooves (it the record when the brake face bears against the rim of the revolving plate. \Vhcn this is done the machine is started in the usual manner and the needle feeds across the record in the ordinary way. W hen the record has been played the needle runs into the idle grooves which occur at the end of every record and while checked at the end of each piece. There has in these grooves carries the standard to such position that the brake piece or member bears agalnst the rim of the revolving plate .thus stopping the machine.

By means of this construction the machine may be started and left to run by itself Without fear of running the spring down or using up the battery if such be used to operate the device. Furthermore, the wear of the needle is prevented as the record is thus been provided a simple and efficient device of the kind described and for the pu pose specified.

It is obvious thatminor changes maybe made in the form anflconstmction of this invention without departing from the material principles thereof. It is not therefore desired to confine the invention to the exact a clip adapted for engagement on a needle carrying element, said clip having a standard receiving opening extending there through, a standard held in said opening to move longitudinally thereof, means to hold said standard in adjusted position in said opening, and a brake member supported, by said standard. v

2. In an attachment for talking machines, a clip adapted for engagement on a needle carrying element, said clip having a stand ard receiving opening extending there through, a standard held in said opening to move longitudinally thereof, means to hold said standard in adjusted position in said opening, a. brake member supported by said standard, and other means to hold said brake member in adjusted position relative to said standard.

In testimony whereof, I atlix my signa ture, in presence of two witnesses,
